HEAD-HOLDER non GBAIN-BINDERS.

Specification of Letters Iatent.

Patented May 22, 1917.

Application filed April 11, 1914. Serial No. 831,104.

To all whom it may concern:

Be it known that I, BERT R. BENJAMIN, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certainnew and useful Improvementsin Head-Holders for Grain-Binders, of which the following is a full, clear, and exact specification.

My invention relates to head holders for grain binders.

In my prior Patent No. 1,029,741, patented June 18, 1912, I have described and claimed a two-partjointed head holder for binders adapted to rotate with the knotter shaft of the binder and normally lie in engagement with the binder deck in such a manner as to prevent the heads of long grain from dropping down and hanging over the binder deck to too great a degree.

My present invention has for its object to improve the construction of such or other head holders of the rotatable type byproviding improved means for attaching a part thereof to the knottershaft whereby the head holder is securedto the knotter shaft and made adjustable with respect thereto in such an improved manner that it may be readily adapted to different grain conditions. I attain these objects by means of improved attaching and adjustlng means for the head holder hereinafter more fully described.

Inorder that my invention may be clearly and fully understood. I U have illustrated three embodiments of it in the accompanying drawings.

In these drawings: Figure 1 is aperspective view of a binder equipped with an improved form of my in vention; i

. Fig. 2 is a similar view looking in the opposite direction;

Fig. 3 is a detail v ew of this form of attaching means;

a Fig. 4. is a sectional view, taken along line 4-4 of Fig. the arrow;

3,"looking in the direction of Fig. 5 is a detail. viewofa modified form of my improved construction; and

Fig.6 isa detail'view of a further niodifled form of the same. s

.Inthe construction shown in Figs. 1 to 4 the bracket member 1. is carried upon the discharge arm 2. which; in turn, is carried on. the knotter shaft binder-4:. and

is rotatable with that shaft in a well-known manner. This bracket 1 is preferably in the form of a casting and is provided with an upper lip, ledge or hook 5 adapted to fit over one of the lateral flanges on the top of the discharge arm, and is also provided with a downwardly extending body portion 6 adapted to lie alongside the web of the discharge arm, which body portion has a lower laterally protrudinglug or ledge 7 thereon adapted to underlie the lip 5 and form therewith a channel in which the arm 2 is received. In this lower ledge or lug 7 an upwardly and angularly disposed opening or slot 8 is formed which is adapted to receive and hold at an angle to the discharge arm the upper end of the upper section 9 of the head holder, which is also preferably cut off angularly so that it may underlie the flange on the oppo-siteside of the arm 2 from the casting 1. In order to clamp the parts securely together a nut and bolt connection 10 is provided which extends through the bracket 1 at a point beneath the discharge armand serves to clamp the member 9 of the head holder to the bracket 1 in the relation shown in Fig. 3. Obviously. when desired. the bracket 1 and the head holder may be adjusted longitudinally of the discharge arm 2 by simply loosening the nut on the bolt 10 and shifting the casting and head holder to the desired position.

In Fig. 5 I have illustrated a modified form of this construction wherein a member 11, corresponding somewhat to the bracket '1, is fixed to the web of the discharge arm by a bolt 12 extending transversely through the web and the casting. This member 11 is provided with a laterally extending lower flange or lip projecting laterally underneath {and beyond the lower edge of the web on the discharge arm, and is also provided with a slot or opening therein] disposed at. an angle to the discharge arm and in substantially the same manner as the vopening 8 previously referred to. Through this opening the upper member 9 of the head holder extends into substantially the same position occupied by it in the construction heretofore described; but in this instance the bolt 12, passing through the web of the discharge arm, serves to directly clamp together the head holder 9, the bracket 11 and the web of the discharge arm. Obviously, in this construction the bracket 11 and the head holding member 9 are both secured to the discharge arm 2 by the'bolt 12, and by providing a longitudinally disposed series of holes 13 the parts may be adjusted longitudinally to vary the position of the head holder as in the construction heretofore described In Fig. 6 I have shown a further modified form of'my construction, wherein, instead of being attached to the discharge arm, the adjustable head holder connection is made to a supplemental arm 14' attached to the knotter shaft 8 by the set screw 15 or any suitable means and protruding radially from that shaft. This member let is provided with a longitudinally extending. slot or channel 16 adapted toreceive the upper end of a curved upper head holding member 17 of substantially the shape of a right angle, a slot and bolt connection 18 being provided between the member 14 and this member 17 so that the latter can be adjusted longitudinally with respect to the former, the member 17 in this instance being provided with the slot, while the bolt is carried by the member 14. I

It will, of course, be understood that the form of my invention shown in Figs. 1, I and 5 may obviously be adapted to use in connection with a supplemental arm projecting radially from the knotter shaft in the same manner as the arm 14 described in connection with the section shown in Fig. 6; or even, in fact, to any member rotatable with that shaft. It is further to be understood that in all'of these constructions a lower swinging head holder member 19 is preferably pivotally attached to the lower end of the head holding member 9, so that, when the shaft 3 is rotated, the two head holding members will move therewith; as, for instance, illustrated in dotted lines in Fig. 6, the lower or swinging head holding member 19 normally engaging with the deck of the binder when the knotter shaft is at rest, and swinging around again into engagement with the deck when the knotter shaft is actuated.

Obviously, in all of these instances, when, upon variation in the grain conditions, the operator desires to vary the position of the heads upon the binder deck, he may readily do so by simply loosening the connection of the upper head holder to the part rotating with the knotter shaft, and then sliding the bracket and head holder longitudinally of that part to the desired position, whereupon, by tightening this connection, the parts are locked. against accidental longi tudinalmovement and relative angular displacement.

While I have in this applicationspecifically described three forms which my invention may assume in practice, it is, of

course, to be understood that the forms 'tioned member.
